DESCRIPTION

The SS6734G is a 3-pin low-dropout linear regulator with superior characteristics, which include zero base current loss, very low drop- out voltage, and output voltage accuracy of 2%. Typical ground current remains approximately 55µA, for loads ranging from zero to maximum. Dropout voltage at an output current of 300mA is exceptionally low. Built-in output current limiting and thermal limiting provide maximum protection against fault conditions. The SS6734G is available in RoHS-compliant SOT-23-3, SOT-89, and TO-92 packages. TYPICAL APPLICATION CIRCUIT SS6734G 1µF COUT VOUT VOUT GND VIN 1µF CIN VIN Low Dropout Linear Regulator (CIN and COUT should be electrolytic capacitors) Pb-free, RoHS compliant.

Note 2: Guaranteed by design. Note 3: Regulation is measured at constant junction te mperature, using pulse testing with a low ON time. Note 4: Current limit is measured by pulsing a short time. Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below the value of the output voltage measured with a 1V differential.
